Dear NHTSA, I am submitting a formal complaint regarding a 2019 Buick Regal, which I purchased as a used vehicle in 2023 with approximately 19,000 miles. Since owning the car, I have added only 14,000 miles, yet I have experienced multiple significant and ongoing issues that raise serious concerns about the safety, reliability, and warranty service associated with this vehicle. Vehicle Problems: Suspension Issues: Shortly after purchase, the car has had persistent suspension problems, which negatively affect stability and ride quality. The dealership has replaced multiple suspension components, but the issue continues and remains unresolved. General Motors (GM) initially agreed to cover these repairs even if my warranty expired and also stated I would qualify for a vehicle buyback. They have now backtracked and are refusing to honor that commitment, despite the ongoing unresolved safety issue Electrical and Transmission Malfunctions: I have reported intermittent electrical and transmission issues to the dealer. These include erratic shifting, hesitation, and occasional system malfunctions. Each time, I have been told they cannot replicate the problems, so no repairs have been made. These issues are intermittent, but they occur while driving and are potentially dangerous. Delays in Repairs and Warranty Coverage: The dealership delayed parts ordering and repairs for my suspension concerns until after my warranty expired. This delay appears to have been intentional, potentially to avoid honoring warranty coverage. Refusal to Service Due to Location (Puerto Rico): I live in Puerto Rico, and both GM and the dealership have stated that they are limited in what they can do for me because of my location. For example, I was told they cannot order a replacement windshield to Puerto Rico, and that what they can do based on a buyback or warranty coverage is limited. I have been patient and waited for the dealership and GM to make things right for 2 years.

My car has had suspension issues for 2 years and I have repeatedly taken the car to the dealership.

Low beam headlights randomly turn off while driving at night and day. Causing not to be able to see the roadway at all. Very dangerous!!! They give no warning at all. Only the low beams do this. Bright lights are not affected. There was a recall for this issue but they said my car was not affected. But it is 100% affected by this recall. Ot seems like the Headlamp driver module is overheating. It gets extremely hot. This issue almost caused a very serious accident .

My daughter owns a 2019 Buick Encore and the check engine light keeps going on. She took her car to the dealer and was told that it needed a Turbo Bypass Valve and Solenoid valve. The car is just a few months within the 10 year powertrain warranty and the dealer refused to cover as defect. She drives on the freeway 45 minutes to/from work and this is a serious issue that causes the engine to rev hard and not stop as well as stall intermittently.

On March 18 , 2025 I purchased a 2014 Buick Encore with an implied warranty, the vehicle had 128,644 miles on the odometer. At the time of purchase the check light was not on and the vehicle had no visible or audible mechanical issues. Not 14 days after purchase there was a strong odor of burning oil due to an oil leak dripping into the splash shield. A certified mechanic advised me that the problem was a very common issue with the 2014 Buick Encore and the oil cooler associated with the turbo charger needed to be replaced. This issue is so common that the NHTSA issued a GM part failure warning for the 2017 model and instructed GM to reimburse all vehicle owners to replace the part (N232395330). This issue clearly a problem that needs to be addressed with the 2014 model as well. My mechanic said that auto dealers are cleaning the splash pad prior to selling the vehicle so that the burning oil smell is not noticeable until 14 days or so after purchase. The repairs cost me $1148.00 just weeks after purchasing the vehicle. This problem of dealers covering up the problem and faulty GM parts needs to be addressed. I believe my vehicle falls under the previous GM parts needs failure warning and I should be reimbursed the cost of the repairs in the amount of $1148.00.
